How Our Work Protects Complex Foundations

Our foundation work spans a wide geographic range. From challenging bog-like soils of Richmond and Delta to the deepest excavations throughout California and into Northern Washington, we have a deep working knowledge of the varied soil, groundwater, and regulatory conditions across these markets.

This breadth means we bring proven, region-specific approaches to every below-grade project rather than a one-size-fits-all method. That range is especially evident in our San Diego work, where we've taken on demanding deep-excavation and foundation projects that test both our engineering and execution knowledge through:

  • High or fluctuating groundwater tables that require careful dewatering and drainage planning
  • Complex and variable soil conditions that affect bearing capacity and excavation stability
  • Construction immediately adjacent to existing structures, where protecting neighbouring properties is critical
  • Shoring requirements to stabilize deep cuts and keep work safe and on schedule
  • Site-specific excavation considerations such as lateral earth pressures, access constraints, and sequencing

    Our Legacy of Excellence in Landmark Projects

    Over the decades, we have partnered with with some of North America’s largest builders and have been instrumental in the construction of some of Vancouver's most iconic buildings.

    • Vancouver House: We provided the critical waterproofing for one of the city's most architecturally complex and recognizable towers.
    • The Butterfly: For this LEED Gold certified landmark, we delivered sustainable and robust Division 7 solutions that met their exacting standards.
    • Olympic Village (2010): Because of our scale and expertise, we were entrusted with 65% of the roofing and waterproofing for this massive, high-profile development.
    • Shangri-La Hotel: We secured the foundation of Vancouver's tallest building, proving that no project is too large or complex.
    • Oakridge Centre: Our reputation and capabilities helped secure a contract to provide waterproofing to Oakridge Centre - one of North America's biggest retail and residential construction sites, with a total planned size of 5 million square feet, and a cost of around $6.5 billion.

    When the project is high-profile and the stakes are high, developers count on us.
